I have a problem. I would like to connect a MacSE30 to a dataline connection. The Hardware is simple -> it uses phone wire with one send data wire, one recieve data wire, and one ground wire. I know these wires. On an IBMPC, DEC terminal, or WYSE50 terminal a 9-pin connector is used, pins 2, 3, 5 as I recall. I have tried this on the mac with a 9-pin to 8-pin connector -> to the mac. This does not seem to work... but I really don't know since all of the communication software I have is for modem connections or appletalk. (Red Ryder, MicroPhone, NCSA Telenet). How can I get what I want? I would really like to know the correct wiring. i.e. which pins (both 8 and 9-pin, but especially 8 pin) on the Mac should be used for data recieve, data send, and ground. Also what software should/can I use? I would prefer an inexpensive solution, i.e. shareware or freeware. BTW this connection is to a PR1ME 6350. My current sol'n is to use a modem to call the PR1ME's modem, but the 9600 bps of the data switch connection is desireable. (Also it doesn't tie up a phone line.) BTW. I know the communication settings necessary are 7 data bits 1 stop bit, 9600 bps, None or Odd parity (I forget)... Well, hopefully someone can help... Thanks in advance! -Brent Schorsch (schorsch@oxy.edu)

If someone has handy an explination of the mac serial port pin connections I would apreciate that as well. -- -george george@mech.seas.upenn.edu

OK. Here it is, straight from Inside Mac, Vol. 4: _____ / 8 7 6 \ | 5 4 3 | \ 2 1 / ----- 1 - Output handshake 2 - Input handshake/external clock 3 - Transmit data - 4 - Ground 5 - Receive data - 6 - Transmit data + 7 - (not connected) 8 - Receive data + As I recall, tying pin 3 & pin 5 to ground gives you RS232 (port is RS423). -- ----------------------------------------------------------------------------- | Glenn L.
